Removal guidelines
A
Removing the drive belt
The following operations are necessary because the engine uses a
serpentine drive system with auto-tensioner.
1. Insert a 12.7sq spinner handle into the auto-tensioner tool hole,
and turn the auto-tensioner in an anti-clockwise direction before
it reaches the stopper.
2. Align hole A and hole B, insert an L-shaped hexagonal Allen
Key, to hold the position, and remove the drive belt.
Caution
If planning to re-use the drive belt, ensure that it will be
refitted the same way round, by marking the back of the belt
with chalk arrows indicating the direction of movement.
B
Removing the power steering oil pump and the A/C
compressor
1. Remove the power steering oil pump and the A/C compressor
from the bracket with the hoses intact.
2. Secure the removed power steering oil pump and the removed
A/C compressor with string, and put them somewhere where
they will not hinder the removal or fitting of the engine ASSY.
C
Removing the transfer ASSY and the transmission
ASSY
1. In order to prepare the special mechanical engine hanger
(MZ203830, MZ203831 or MB991928), the radiator support
upper insulator mounting bolts should be tightened on the
chassis (2 places).
2. Remove the transfer ASSY and the transmission ASSY.

Fitting the engine mount bracket & stopper ASSY
1. Support the engine oil pan component with the garage jack
through the engine block, and fit the engine mount bracket &
stopper ASSY whilst checking the position of the engine. Fix the
engine mount stopper so that the arrow points in the direction
shown in the diagram.
2. Support the engine ASSY with a garage jack.
3. Remove the chain block.
4. In the same way as when it was removed, hold the engine
ASSY with the special tool.
(1)
(MZ203830 or MZ203831)>
Install the special mechanical engine hanger (MZ203830
or MZ203831).
(2)
Fit the following parts to the base hanger.
• Slide bracket (HI)
• Foot (standard) (MB991932)
• Joint (90) (MB991930)
Install the special engine hanger (MB991928)
